Sample Program: GetAlarmInfo with S7-1500

Hi,

one of the innovations of the SP1 for STEP7 V12 (Released for Delivery at http://support.automation.siemens.com/WW/view/de/76276623) is the inclusion of new instructions, like GetAlarmInfo for S7-1500.

With this instruction it is possible know if an alarm is active/acknowledged in S7-1500.

Here there is a very simple sample project to illustrate how it works.

It has a very simple S7-1500 program and a HMI for data monitoring

TIP:
The block Get_AlarmState returns values that are incorrect according to the documentation.
Bit0 (Alarm Log Status: Incoming / Outgoing) always shows the wrong state.
Bits1+2 (Alarm Log Status: Bit1 = Incoming with ack. / Bit2 = Outgoing with ack.)
Bits1+2 show:

When alarm log is incoming: 0+1 (means according documentation: alarm log outgoing with ack.)
When alarm log is outgoing: 1+1 (means according documentation: alarm log incoming with ack. and outgoing with ack.)
